Industrial wastewater advanced treatment system

Abstract

The invention discloses an industrial wastewater advanced treatment system which comprises an adjusting tank, a reaction sedimentation tank, an aerobic tank, an anaerobic tank, a secondary sedimentation tank, a filtering device, a detection tank and a disinfection tank which are connected in sequence, and the disinfection tank is provided with an up-to-standard discharge pipeline; the reaction sedimentation tank, the aerobic tank, the anaerobic tank and the secondary sedimentation tank are respectively connected with a sludge concentration tank for mixing sludge and concentrating the sludge through pipelines, and supernatant in the sludge concentration tank flows back to the regulating tank through a pipeline for secondary sewage treatment; the filtering device comprises a multi-medium filter, an activated carbon filter and an RO membrane filter, a detection device for detecting the nitrogen content, the phosphorus content and the heavy metal content in purified water is arranged in the detection tank, and the detection tank is connected with the reaction sedimentation tank through a pipeline. The industrial wastewater advanced treatment system is reasonable and effective in structural layout and low in cost, and has a good advanced treatment effect on industrial wastewater.

Description

Technical field [0001] The invention relates to the technical field of wastewater treatment, in particular to an industrial wastewater advanced treatment system. Background technique [0002] In recent years, with the rapid development of urban economy, the amount of sewage generated in the process of industrial production in cities has gradually increased. Industrial wastewater contains industrial production materials, intermediate products, by-products and production processes that are lost with water. The pollution is an important cause of environmental pollution, especially water pollution. [0003] In the prior art, the process of industrial wastewater treatment is relatively simple, mainly using aerobic biological treatment and anaerobic biological treatment techniques represented by activated sludge method or biofilm method, and auxiliary treatment by physical or chemical methods. Although the activated sludge method or biofilm method has little impact on the environment, t...
